    • Disclosed is a homogenization filter (6) for an optical radiation field pertaining to an illuminating beam (2), whereby said filter cooperates with a diffusion screen (9) in order to homogenize light intensity in an image plane. The inventive filter comprises a transparent substrate (12) on which a grid consisting of light-proof surface elements (13) is placed. The homogenization filter (6) can, for instance, be used in the reflected light or transmitted light beam (2) of a microscope in a conjugate position, e.g. close to the collector (5). A diffusion screen (9) that is usually present in the plane of the aperture stop is used to blur the shadows in the illuminating beam produced by the surface elements (13). By varying the surface ratio between the non-coated and coated surface of the substrate, local transmission values can be produced at any point of the homogenization filter as desired, and radial and non-rotationally symmetrical inhomogeneities can be compensated.
    • 提供了一种用于照明光束路径(2),其实现的光强度的均匀化中的图像平面在合作用透镜(9)的光学辐射字段中提供的Homogenisierungsfilter(6)。 它由在其上施加不透明表面元件(13)的栅格的透明基板(12)的。 所述Homogenisierungsfilter(6),例如,在反射光或透射光照明光束路径(2)在一个平面上共轭的像平面位置的显微镜,例如 在收集器(5)的附近,被使用。 甲在孔径光阑平面透镜(9)公知的是利用抹杀的元件的表面中的照明光束路径中产生(13)的影子(2)。 通过改变非沉积,和气相沉积基板表面所需的局部透射值之间的表面比可在(6),并且因此径向和非旋转对称的不均匀性进行补偿的Homogenisierungsfilters的任意点来生成。
